Log Into Cable Modem Through Router
ignored by most people, cable modems have a diagnostic that can help you troubleshoot connection problems. What Diagnostic Page? Unbeknownst to most people, cable modems (and other broadband modems) have diagnostic and logging functions built in, just login to cable modem like routers. While some people do occasionally peek at the control panel of their router, very few people ever look at their modems-or even realize they can do so. RELATED ARTICLEHow to Troubleshoot Your Internet Connection, Layer-By-Layer So why look at the diagnostic page and logs of your cable modem in the first place? Think of this familiar scene: something weird is going on with your internet access, so you dutifully unplug comcast cable modem login your modem and router, start them back up, and things work well again…for a spell. Or maybe your internet connectivity drops out intermittently and no amount of tinkering with your router has solved your problems. While we all tend to over-focus on the router as the source of potential problems, oftentimes the modem (or the line it's connected to) can be at fault. In those cases, you need to peek into the modem to see what's going on. By accessing the tiny little web server hidden inside your modem and reading the diagnostic pages, you can learn a ton of things about your modem and connection like general status, signal strength, and event history via the system log. Armed with that information you can then say something like "Okay, it's not the modem or a signal strength issue, so I'll focus on the router and other elements of my network" or "Something is clearly going on with the modem so I'll call the cable company." We want to emphasize that last part. Even if the diagnostic control panel in your modem does have user-editable settings (which is very rare), you shouldn't mess around with that stuff unless expressly instructed to do so by your internet service provider.

Tags: cable modem, access, signal level, status, signal, SNR Although settings are not user-editable, most cable modems have built-in diagnostics and status pages accessible http://www.howtogeek.com/240575/how-to-read-your-cable-modems-diagnostic-page-when-something-goes-wrong/ by the end user that provide useful information, such as signal levels, SNR (signal-to-noise ratio), logs of events, firmware version, etc.To access your cable modem status/diagnostics pages, open your web browser and navigate to one of the following pages:Arris, Motorola, Scientific Atlanta, RCA, Terayon: http://192.168.100.1SMC: http://10.1.10.1 (username: cusadmin pass: highspeed)3Com: http://3comcablemodem.com or http://49.112.50.65 (username: User pass: Password)Notes: We have an extensive database of 2600+ cable modems and routers with their respective http://www.speedguide.net/faq/how-to-access-signal-levels-and-logs-on-my-cable-391 IPs and default passwords available here: Broadband Hardware Database If the above IPs do not work, you can try setting your client to a static IP in the 192.168.100.x range (255.255.255.0 subnet mask), then try again.If a username/password is required, you may want to try admin/motorola, admin/w2402. admin/password, root/root Post your review/comments rate: -- rating -- 5 - Excellent 4 - Good 3 - Average 2 - Poor 1 - Very Poor avg: Popular Is 5GHz Wireless better than 2.4GHz ?

T3 and T4 timeouts are described in much more detail elsewhere in this blog, however this post provides a high level overview of the various timeouts as a reference. Thanks to baranek110 for the tutorial located on Cable-Modem's Blog. T1 Timeout ( No UCD’s received ) Explanation: The cable modem has not received any periodic Upstream Channel Descriptor (UCD) messages from the CMTS within the timeout period. This error message is DOCSIS event message is U01.0, Upstream Channel Descriptor. T2 Timeout ( No Maintenance Broadcasts for Ranging opportunities received ) Explanation: The cable modem did not receive a broadcast maintenance opportunity in which to transmit a Ranging Request (RNG-REQ) within the T2 timeout period (approximately 10 seconds). The cable modem is resetting its cable interface and restarting the registration process. This error message is DOCSIS event message is R01.0, Ranging Request. T3 Timeout ( Ranging Request Retries Exhausted ) Explanation: The cable modem has sent 16 Ranging Request (RNG-REQ) messages without receiving a Ranging Response (RNG-RSP) message in reply from the CMTS. The cable modem is therefore resetting its cable interface and restarting the registration process. This typically is caused by noise on the upstream that causes the loss of MAC-layer messages. Noise could also raise the signal-to-noise ratio (SNR) on the upstream to a point where the cable modem’s power level is insufficient to transmit any messages. If the cable modem cannot raise its upstream transmit power level to a level that allows successful communication within the maximum timeout period, it resets
